| Amino acid sequence | MGSSHHHHHH SSGLVPRGSH MGSSFLSPEH QRVQQRKESK KPPAKLQPRA LAGWLRPEDG GQAEGAEDEM EVRFNAPFDV GIKLSGVQYQ QHSQALGKFL QDILWEEAKE APADK. |
| Description | Ghrelin Human Recombinant contains 115 amino acids (24-117 a.a.) and a total molecular mass of 12.8 kDa. The GHRL is fused to a 20 amino acid His Tag at N-terminus and purified by proprietary chromatographic techniques. |
| Expression host | Escherichia Coli. |
| Formulation | The Ghrelin protein solution contains 20mM Tris-HCl, pH-8 & 10% glycerol. |
| Protein Background | Obestatin is a hormone that is produced in the cells lining the stomach and small intestine of several mammals including humans; it drastically reduces appetite in mice and is expected to do the same in humans. Obestatin is a peptide hormone – a relatively small protein. It is encoded by the same gene that also encodes ghrelin, a peptide hormone that increases appetite. The protein produced by that gene breaks into two smaller peptides, ghrelin and obestatin. Ghrelin is an endogenous ligand for the growth hormone secretagogue receptor and is involved in regulating growth hormone release. Ghrelin is derived from a preprohormone called preproghrelin, which also generates a second peptide called obestatin. Ghrelin is an endogenous ligand for the orphan G protein-coupled receptor GPR39 and is involved in satiety and decreased food intake. |
| Purity | Greater than 90.0% as determined by SDS-PAGE. |
| Reagent Appearance | Sterile filtered colorless solution. |
| Solubility | Add deionized water to a working concentration approximately 0.5mg/1ml and let the lyophilized pellet dissolve completely. |
| Stability | Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles. |
| Synonyms | Appetite-regulating hormone precursor, Growth hormone secretagogue, Growth hormone-releasing peptide, GHRP, Motilin-related peptide, M46 protein, Ghrelin, Obestatin, MTLRP. |
